TOOTH-POWDER HOLDER.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed August 21, 1907. Serial No. 389,597.

To all whom it may concern:

Be it known that I, PII-ILIP S. HAY, citizen of the United States,residing at Mont omery, in the county of Montgomery and btate ofAlabama, have invented certain new and useful Improvements in ToothPowder Holders, of' which the following is a specification.

This invention contemplates certain new and useful improvements inholding and dispensing devices or containers for ulverulent orcomminuted substances, an relates 1n its present embodiment to a holderdesigned to contain and dispense tooth powder.

The invention has for its object a simple and efficient device of thischaracter, the parts of which may be cheaply manufactured and easilyassembled and which may be readily manipulated to dispense aredetermined quantity of tooth powder a ong the bristles of the toothbrush at each operation of the valve or cut off of the device.

With this and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certainconstructions andarrangements of the parts. that I shall hereinafter fully describe andthen point out the-novel features in the appended claims.

For a full understanding-of the invention, reference is to be had to theaccompanying drawings, in which:

Figure 1 is a erspective view of a ortion of a tooth pow er holderconstructe in accordance with my invention; Fig. 2 is an elevationthereof; Figs. 3 and 4 are transverse sectional views illustrating theparts in different positions; Fig. 5 is a detail perspective view of thecut-off; and Fig. 6 is a transverse sectional view of a modified form ofcut-0H".

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawing, the numeral 1 designates the body of theholder and 2 the tubular neck thereof. The said neck is formed with alongitudinally extending discharge opening 3 designed to be controlledby the cut ofl 4 which in the present instance is in the form of a lonitudmally extending plate somewhat curve in cross section as shown. Thesaid out off 4 is formed at its ends with ears 5 and 6, said earsbeingvaper- I tured to receive the shaft 7 upon which the device ismounted to turn, sald shaft being located referablyin an eccentricposition within the neck 2 and journaled at its ends in the head 8 andin the strip or bar 9, as clearly illustrated in the drawing. One of theears of the cut off is extended beyond its pivot point as indicated at10, and a depressor rod 11 is secured at one end to sald extension andextends outwardly through the neck, being provided at its outer end withthe thumb-piece or disk 12. v is encircled by a helical spring 13bearing against the disk 12 and the outer side of the neck 2 and havinga tendency to move the rod 11 outwardly so as to swing the cut off plate4 over the openin 3 to close the latter. The cut off 4 is .provi ed witha plate like extension 14 Wlllch extends longitudinally as shown andwhich isadapted to abut with its edge against the inner side of the neck2 when the cut off is moved away from the openin 3. The neck 2 is formedwith an inward iy extending lip 15 at the opening 3, said lip beingcurved to correspond to the curvature and are of movement of the cut off4. If desired, it is manifest that the said lip may be formed of themetal which is cut to produce the opening 3, being bent inwardly fromone edge of said opening.

In the practical use of my im roved tooth powder holder and dispenser, te user may,

- y merely pressing his or her thumb on the depressor rod 11 swing thecut off 4 awa from the opening 3, this movement ObVlously resulting incausing the extension 14 to abut against the inner Wheel of the neck 2,the pro ortions of the parts being such that When t is contact takesplace the cut ofl 4 at its opposite edge will not project beyond theinner edge of the Ii 15, but will overlap .said li to an ap recia leextents Hence it is evi ent that t e discharge opening 3 will be cut offfrom the remainder of the neck and body portion of the holder and only.such powder as lies within the bounds of the cut off with its extension14 will be permitted to dro through the opening 3 on the brush held uner the same.

It is clear that the amount of powder to be discharged at each operationof the device may be varied by merely changing the relative position ofthe plate extension 14 with respect to the main portion of the cut off.In Fig. 6 is showna modification in which the inwardly,

said plate extension, designated 14, is bent which may be easilyoperated and which will dispense only a certain quantity of powder ateach operation.

Having thus described the invention, what is claimed as new is:

1. A device of the character described, comprising a body, a necksecured thereto and formed with a longitudinal discharge opening,a'cut-ofi mounted within the neck and extending longitudinally thereofand adapted to close said opening, said cut-off being provided at itsends with ears ivotally mounted within the neck, one 0 said ears beingformed beyond its pivot with an extension, a depressor rod secured tosaid extension .and projecting outwardly through the neck, and a springsecured to said rod and tending to move the same outwardly.

2. A'device of the character described,

comprising a body portion, a neck secured thereto and formed with adischarge opening and a lip extending inwardly from one edge of saidopening, a cut off mounted within the neck and adapted to close saiddischarge opening and move over the lip, and means for moving said cutoff, said out off being provided at one side with an extension, and theosition of said extension with the neck and ip being such that the edgeof the extension will abut against the inner wall of the neck when inthe open osition.

3. A device 0 the character described, comprising a body, a neck securedthereto with an extension adapted to abut againstthe inner wall of theneck upon the actuation .of the cut off away from. the dischargeopening, and the neck being formed at one edge of said discharge 0 eningwith an inwardly extending lip co orming to the arc of movement of theout off.

4. A device of the character described, comprising a body, a necksecured thereto and formed with a longitudinal discharge opening, a cutoff mounted within the neck and extending longitudinally thereof andadapted to close said opening, said cut off being provided at its endswith ears, a shaft extending longitudinally within the neck and on whichthe ears are pivotally mounted, one of said ears being provided beyondits pivot with an extension, a depressor rod secured to said extensionand projecting outwardly through the neck, and a' spring encircling theouter end of said rod and tending to move the same outwardly, the saidout off being provided at one side with a plate like extension, for thepur ose specified, and the neck being formed wit a li extending inwardlyfrom one edge of the ischarge opening and conforming to the direction ofmovement of the cut oif away from said 0 ening.

In testimony whereo I afiix my signature in presence of two witnesses.
